GENERAL GEOLOGY

Detailed explanation-1: -Shale is a sedimentary rock which gets exposed to intense heat and pressure under the Earth’s crust making it the metamorphic rock called Slate.

Detailed explanation-2: -Slates are formed from fine-grained sediments such as mudstone and shale.

Detailed explanation-3: -Slate is another common metamorphic rock that forms from shale.

Detailed explanation-4: -Barrovian Metamorphic Rock Changes Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, and then through phyllite, schist, and gneiss.

Detailed explanation-5: -Shales that are subject to heat and pressure of metamorphism alter into a hard, fissile, metamorphic rock known as slate.
